Riptide Fee Management

Overview

Riptide Fee Management is an enterprise-grade fee calculation and distribution service for government and regulated organizations. It provides centralized fee structure management, dynamic calculation engines, multi-party distribution logic, and comprehensive audit trails—enabling agencies to maintain accurate, compliant, and transparent fee processing across their service portfolio.

Purpose

Traditional fee management embeds calculation logic directly into application code, creating maintenance nightmares when fee structures change, regulations evolve, or new services launch. Riptide Fee Management solves this by:

  1. Centralizing all fee structures in a single, version-controlled repository
  2. Supporting historical fee lookups for retroactive calculations and compliance audits
  3. Enabling formula-based calculations that reference other fees and business context
  4. Automating multi-party distributions with configurable accounting codes
  5. Providing workflow integration for seamless fee calculation within business processes
  6. Generating comprehensive audit trails for regulatory reporting and reconciliation

Key Capabilities

  • Dynamic Fee Calculation: Execute fee calculations using fixed amounts, formulas, tiered structures, or percentages
  • Historical Fee Support: Calculate fees using structures effective on any past date for retroactive processing
  • Multi-Party Distributions: Automatically split fees across multiple accounting codes with percentage or fixed-amount rules
  • Tenant Isolation: Complete data separation for multi-tenant government platforms
  • Workflow Integration: Native integration with Riptide Platform workflow engine for automated fee processing
  • Formula Engine: Support complex calculations referencing other fees, context variables, and conditional logic
  • Comprehensive Audit Trail: Track every calculation with full context for compliance and reconciliation
  • Performance Optimized: Designed for ≥2000 calculations per minute with sub-500ms P95 latency

Fee Calculation System

Riptide Fee Management supports multiple calculation methods to accommodate diverse business requirements:

  • Fixed Amount: Simple flat fees ($100.00)
  • Formula-Based: Dynamic calculations (base_amount + (expedited ? expedited_fee : 0))
  • Tiered Structures: Range-based fees (e.g., entity value tiers)
  • Percentage Calculations: Proportional fees based on transaction amounts
  • Historical Calculations: Use fee structures effective on specific dates
  • Distribution Rules: Automatic splitting across accounting codes with priority ordering

Integration Points

  • REST API: Calculate fees and manage structures from any application via HTTP endpoints
  • Workflow Engine Integration: Automated fee calculation steps within Riptide Platform workflows
  • Platform SDK Foundation: Built on Riptide Platform SDK components (Logging, Configuration, Monitoring, Tenant Isolation)
  • Caching Layer: High-performance in-memory caching for frequently accessed fee structures
  • Configurable Persistence: Entity Framework Core with pluggable database providers (SQL Server, PostgreSQL, others)
  • Observability: OpenTelemetry distributed tracing via Platform Monitoring SDK
